Abstract
This paper presents an alternative means for measuring the Iddt current degradation with circuit ageing. MOS devices for CMOS process technologies below 45nm are known to be susceptible to ageing effects such as BTI and HCI. The correlation between the supply current degradation and the propagation delay degradation is shown to provide crucial information in monitoring circuit ageing. Ageing analysis were conducted for various CMOS circuits and the ALU of OpenRisc 1200 processor using 32nm process technology. Results showed that the Iddt current degradation may vary up to -11.97% compared to delay degradation of 7.15% of the same critical path. A significant Iddt current degradation of -23.34% can be observed for the ALU circuit block. Evaluating the Iddt current degradation in a wider perspective provides not only a better percentage change, it also provides a much bigger absolute current.
